Weird issue with PHP5

I have a module originally written for PHP-Nuke that I have ported to CPG-Nuke/DragonFlyCMS. In PHP4, the page I'm displaying works fine. In PHP5, it doesn't. The following link is a screenshot of the page using PHP4: http://nukeleaguedf.winsto.net/working-php4.jpg And a screenshot from PHP5: http://nukeleaguedf.winsto.net/broken-php5.jpg You can see that the stat lines for the first group (Batters) displays properly. However, the stat lines for the following groups do not. I have copied the three offending files into text files: http://nukeleaguedf.winsto.net/modules/League/index.txt http://nukeleaguedf.winsto.net/modules/League/util.txt http://nukeleaguedf.winsto.net/modules/League/classes.txt Line 1119 of index.txt is where is all begins. I have tested that the while loop is actually looping 3 times as it should (once for each group). Doing a var_dump of $players shows all of the required information. Line 1126 is the actual line that displays the fields. I have scoured the code with my limited PHP knowledge, but I can't for the life of me see why its not working in PHP5. Perhaps part of the code is incompatible with PHP5, or perhaps its a bug in PHP5. Is anyone able to help?
